Barnard Substation upgradeMeeting demand in Burnaby and Coquitlam

To meet the growing demand for electricity in Burnaby, we’re upgrading the Barnard substation, located in Burnaby near Gaglardi

Way. The scope of work includes:

○ Replace old circuit breakers and existing relay buildings in the 60kV yard with a new relay building.

○ Construct a new building and install indoor switchgear to replace existing aging outdoor feeder section.

○ Replace end-of-life protection, control and metering equipment.

○ Remove existing feeder section after load has been transferred.

○ Remove abandoned structures.

○ Restore any ground disturbance.

WHAT IS BARNARD SUBSTATION?

Barnard Substation is a distribution substation built in 1950s that takes electricity at higher voltages (230kV) and down convert it

to 12kV for supply of power to homes and businesses in the neighbourhood. There is also a switching function for the 60kV

transmission lines that goes through Barnard Substation.

Over 36,000 customers are being served by Barnard substation. This number is expected to grow as density in the area

increases. The current area Barnard substation serves is west to Lake City Way and east to Mariner Way.

WHAT’S THE BENEFIT OF THIS UPGRADE?

This upgrade will provide increased reliability to the electrical system and address near end-of-life equipment. Upgrades to the

substation from oil-filled equipment of the 1950s to new modern equipment will also increase safety for our workers and the

public. This upgrade will also prepare for future growth in the area and allow homes, businesses and industries to continue

to grow.
